the core functionality of RPerl is to generate C++ output code from Perl input code, so no matter what we do we will be generating C++ output code, even if we have to create our own C++ async libraries

but RPerl is NOT meant to be like Perl5i or moe or other projects which break backward compatibility w/ Perl 5, all our new RPerl features (such as SSE support which already exists) are implemented as add-on features which do not break Perl tiself
